A label class that supports displaying an active hyperlink.
KURLLabel is a drop-in replacement for QLabel that handles text in a fashion similar to how an HTML widget handles hyperlinks. The text can be underlined (or not) and set to different colors. It can also "glow" (cycle colors) when the mouse passes over it.
KURLLabel also provides signals for several events, including the mouse leaving and entering the text area and all forms of mouse clicking.
A typical usage would be something like so:
KURLLabel *address = new KURLLabel(this); address->setText("My homepage"); address->setURL("http://www.home.com/~me"); connect(address, SIGNAL(leftClickedURL(const QString&)), SLOT(processMyURL(const QString&))); |
In this example, the text "My homepage" would be displayed as blue, underlined text. When the mouse passed over it, it would "glow" red. When the user clicks on the text, the signal leftClickedURL() would be emitted with "http://www.home.com/~me" as its argument.

bool |
[const]
When this is on, the text will switch to the selected color whenever the mouse passes over it.
bool |
[const]
This feature is very similar to the "glow" feature in that the color of the label switches to the selected color when the cursor passes over it. In addition, underlining is turned on for as long as the mouse is overhead. Note that if "glow" and underlining are both already turned on, this feature will have no visible effect.
const QPixmap* |
[const]
Returns: the alternate pixmap (may be 0L if none was set).
void |
[slot]
Turn on or off the underlining.
When this is on, the
text will be underlined. By default, it is true.
void |
[slot]
Sets the URL for this label to url.
void |
[virtual slot]
Overridden for internal reasons; the API remains unaffected.
void |
[slot]
Turn on or off the tool tip feature.
When this is on, the URL will be displayed as a
tooltip whenever the mouse passes passes over it.
By default, it is false.
void |
[slot]
Specifies what text to display when tooltips are turned on.
If this is not used, the tip will default to the URL.
void |
[slot]
Set the highlight color.
This is the default foreground
color (non-selected). By default, it is blue.
void |
[slot]
This is an overloaded version for convenience.
void |
[slot]
Set the selected color.
This is the color the text will change
to when either a mouse passes over it and "glow" mode is on or
when it is selected (clicked). By default, it is red.
void |
[slot]
This is an overloaded version for convenience.
void |
[slot]
Turn the custom cursor feature on or off.
When this is on, the cursor will change to a custom cursor (default is a "pointing hand") whenever the cursor passes over the label. By default, it is on.
Parameters:
void |
[slot]
Turn on or off the "glow" feature.
When this is on, the text will switch to the
selected color whenever the mouse
passes over it. By default, it is true.
void |
[slot]
Turn on or off the "float" feature.
This feature is very similar to the "glow" feature in
that the color of the label switches to the selected
color when the cursor passes over it. In addition,
underlining is turned on for as long as the mouse is overhead.
Note that if "glow" and underlining are both already turned
on, this feature will have no visible effect.
By default, it is false.
void |
[slot]
Set the "alt" pixmap.
This pixmap will be displayed when the cursor passes over the label. The effect is similar to the trick done with 'onMouseOver' in javascript.
